You can also issue your concerns on something on a more public basis without breaking (local) law or stopping business. Of course, does Apple have to do it? No. Should they strongen their efforts? Maybe yes.
I think this is a good point. Even though local law has to be respected, Apple almost always is one of the front runners in ethical or cultural discussions for the better, which is definitely a good thing. But what people remark is that Apple is not really keen on fighting for the freedom of speech in China even though being heavily dependent on the Chinese market and industry.
